Newbie to Marine Velvet

[Reef_Box]

So a about 5 months ago, I had a catastrophic event in my tank. I had 7 fish die in the matter of 3 days. All evidence pointed to Marine Velvet. I tried to do the QT thing and failed miserably. I killed 2 additional fish trying to QT in a 10g tank. I have a small place so I didn't have many options. Rather than killing the last 2 fish in my tank, I decided to just let them pass away in their home. Well that was 5 months ago and I have 2 fish in my tank living with no signs of sickness at all.

My question is this: Do I need to need to pull these 2 fish, run them through QT, and leave my tank fallow for the standard 75ish days, or am has everything run it's cycle?

I obviously don't know what I am doing here.

Tank is a 120g SPS tank, so I have just been focusing on corals for the last 5 months rather than fish. Now wife is asking when we can get fish.

Were these fish exposed to velvet during the outbreak? If so, they might have immunity and the parasite could still be lurking under the radar in your tank. I would play it safe and remove them for 6 weeks. Most people say that is the fallow period for velvet. Velvet is a nasty one. You will probably want to quarantine new purchases anyway so you could add a couple of new fish to the hospital tank with your existing two. Six weeks is probably a good protocol for quarantine anyway. 20 or 29 gallons make good hospital tanks. Good luck.

Excellent advice.
